Development of Robust Wall Modelling for Practical Aerodynamic High Fidelity Prediction Phd


Eddy-resolving methods have gained enormous interest in turbulent flow simulations recently as they rely much less on problem-dependent Reynolds-averaged based closure models (also known as RANS). Without any stringent requirements in fully resolving the wall turbulence, WMLES (Wall-Modelled Large-Eddy Simulations) has shown great promise.


However, unphysical separation bubbles (often laminar) can often occur in applying WMLES, especially near the leading edge where the flow experiences a certain amount of adverse pressure gradient. This poses a potential significant drawback to the application of WMLES to practical aerodynamic predictions where Reynolds numbers are high and strong adverse pressure gradients are almost unavoidable.


The proposed project investigates how efficient methods of introducing the onset of turbulence via external forcing can mitigate the problem and can be practically useable. More fundamentally, the project will look into a “relaxation principle” in the log region of the turbulent boundary layer that could naturally allow turbulence onset to take place without any external forcing.


The project will utilise national and regional high performance parallel computing resources to conduct high fidelity numerical simulations. A hierarchy of test cases of practical meaningfulness will be considered, including the publicly available Airbus XRF1 configuration.
